What is an API?
API stands for Application Programming Interface and it's essentially a doorway into an application.
Using this doorway, other third-party applications can get access to all of the data and features without needing to provide any custom code or integrations whatsoever.
The process works something like this.
An API request is sent to the application. An API request is just a simple HTTP message with some parameters telling the app what information to send back. This response will be sent back usually in JSON or XML format.
The beauty of APIs is that anyone can access information and features that would otherwise be unobtainable.
For example, most of us do not have access to a worldwide network of weather stations, but, anyone can build a mobile app and use APIs to request the data from the already existing weather application.
APIs have become so widespread, you would be hard-pressed to find a popular application these days that doesn’t offer API access.
With this amount of access to APIs, the possibilities are endless.
For those of you new to this also understand that the word "interface" just means where two things meet. Some people think interface just means user interface. It can also be used in terms of database interface, network interface, software interface, urban wilderness interface, land sea interface etc. I've been looked at strangely by people who thought it only meant graphical user interface (GUI).
Thanks
ong thanks a lot, you clear my mind, so much thanks
It is actually a systems theory concept. Something that connects two different systems
@@carlosargelioarevalomercado It's much broader than that. That is one example of an interface.
@@pedrolopez8057 much broader than systems theory?
"Babe wake up, new CertBros dropped"
This cracked me up 😂😂😂
This was damn funny reading the comments.
😆😆
The video is explaining the concept of Web APIs, specifically, not APIs themselves. An API is just the collection of classes, methods and functions exposed by a programming library or framework. Web APIs is the same concept, but brought to the Internet. It's important to know the difference.
People using this video to learn are not at the level where that distinction makes a difference.
@@hastyscorpion All the more important to learn things right from the get go. They are learning a definition of API that's not 100% accurate, they will probably encounter the concept of an API (a real software API) at some point in their careers and get it wrong. Hopefully this won't cost anyone an opportunity in job interviews.
That's not true. There are different levels to learning. Starting from teaching a person 1 + 1 without necessarily teaching them immediately 6578 +-* 7655 doesn't mean 1 + 1 is wrong.
This is just an 11 minutes video. You don't expect them to touch all aspects of API. No person that wants to get serious knowledge about a topic would just watch an 11 minutes video and that's all. There's hours and hours of lectures they know they have to learn but they'll have to START from somewhere.
@@amaechiwilliams1345 I agree that anyone seeking to learn more about this will watch a lot more videos on it. And I do agree that this video is a good introduction to the topic of Web APIS, a good starting point. That being said, I don't think it was too difficult to explain that there is something called APIs and another thing called Web APIS. This is still a simple enough concept that can be explained in layman's terms without getting to deep into the details.
Very true....when I started my backend development learning journey, I found everywhere the same definition, "an API is the set of rules and protocols which enables the communication among different systems".
While this definition is theoretically correct but it doesn't tell the whole picture like what an entity it is and due to this I was just stuck, frustrated, and confused about a month. It was later when I got to know that the APIs are just the classes and methods exposed by a service or system to the users in a specific pre-defined rules and protocols. So basically they standardised the communications between the systems by providing a set of functions and classes to call the actual function classes or methods of the system/services.....As an extra layer of methods above the actual functions/methods.
As a gamer and one who has used addons for games, I’ve heard of APIs for almost 20 years. I be honest to say as much as I’ve heard of the thing, I knew they did a query to the server of the MMO games I played, I’ve never had any idea how they worked. Not clearly. This was a very good example with the video in clear explanation. This has also given me an idea for my job in industrial automation.
Thanks for the quick short introduction
It was really so helpful
Great explanation. I would add: if you’re thinking about doing this as a business, we forewarned that big companies do ‘change the rules’ for their API access whenever they wish, including starting to charge large fees.
Amazing explanation! Truly valuable, I can say I learnt so much from this channel about technology than what lecturers in schools have taught.
Thank you for creating this video. I've been hearing this "API" long ago but never understood it until today thanks for this video.
thank you so much! i didnt understand APIs when told about them but your explanation was amazing
Well presented in simple and digestible format
A voice made for radio! Thanks for the video.
Great and very clear explanation! Thank you so much!!! 😊👍
Love it. Very explanatory.
I love api and ur videos they just make the internet better
Allah razı olsun ♥ Çok bilgilendirici bir video ♥
Nice video, i understand APIs better now. Thank you
Your explanations are amazing. Nice pace, great animations & examples.
Awesome! The CRUD analogy, I've one other place earlier
explanations are in a very clear way thank you for the tutorial:)
The best video on API ever, I found.😄
thank you very much when i saw the title of the video i was saying the exact same API's was giving me a hedace to understand thank you
Very nice description. Thank you :)
Greatest API video I've ever seen!!!
Important to note that this is just HTTP/Web APIs
APIs exist way out of the scope of web apps or Http
it is one of the best explanations ever.
This video is about REST APIs. It is misleading to beginners as it will make them think that all APIs are REST/HTTP. The title should say "REST APIs."
THIS. Web devs especially influencers aren't very smart
what’s the difference?
Really Amazing Explanation..
Brilliant, keep up the great work
Channelling my inner John Tuld (Margin Call): "Please, speak as you might to a young child or a Golden Retriever. It wasn't brains that got me here, I can assure you that." You did, and now it's finally sunken in! Thank you 👍
Love this!! Really happy you liked it 😁
@certbros O passed CCNA today and i want to thank you for all the awesome videos you have.They sure helped me ...
Congratulations on getting your CCNA Jennifer!!! Happy to have helped. Keep up the great work.
If only I could give this video many likes :) Well explained, especially for a beginner
Thanks! Very well explained imho.
Thank You for explaining in detail, slow and steady manner. It really helped me to understand the concept of API with actual practical example rather than reading definitions here and there.
very digestible. well done
Hey, it is nice not to be scared of APIs anymore 😂. Great job 🎉
Great explanation, thanks a lot...
I had no idea how much I needed this hahaha thanks new sun here
FINALLY. I get it. Thank you!
Spectacular as always
Thank you Tonio! Appreciate the kind words 🙏
Amazing explanation

Nice. Finally a high level detailed overview of API's explained in a way that someone who's not that familiar with API concepts will be able to grasp. Much appreciated.
Good stuff my man!
Good explanation, thx
Fantastic tutorial
Excellent video!
thank you, great video
Thank you so much sir 🙏
wonderful content!
This is BY FAR the best API explanation on CZcams. Thank you!
Wow this, I like how you broke down everything with examples. I was wondering what JSON format is and how I would have gone to look for another video to understand that but you broke everything down with examples. Lovely
Thank a lot :) well explained
Thank you so much for this
This is really entertaining 😍😍😍😍😍😍
Thank you Attouchi!
Great video. Thanks!!!!!!!!!
thanks. that was useful.
The first 3 seconds proved this fella understands my pain
We've all thought it! 😂
Best explanation!!!!
nice video explanation thanks
Amazing!!!! Thanks
Thank you for making videos, learned soooo much from this channel!
Really happy to hear that Justin! You're welcome and thank you for comment 👌
Best explanation!
Thank you Mohammad!
Very well explained to a noob like me up until the point where I asked myself: So how is the response received and do you need to run it through a service like postman or was that just for the display?
Thank you so much
I already knew what is API still i watched complete video because you are #$÷*@ing awesome
Thanks man! Really appreciate it. That's why you're awesome too ☝
Really great channel, I learned a lot of things, thank you so much.
You're very welcome! Happy to help.
Well done.
Thank you!
You earned the subscribe on this one
Excellently explained! !!!! Thank you soooo soooo much.
liked and subscribed. for a whole week, I've been searching for an explanation that could make me understand APIs. This was it!
The thumbnail was exactly the question i had in my head.
Absolutely brilliant! Thank you!
thank you sooo much
So clear
Great information and nicely done👍
Thanks Orley! Really appreciate it 👍
I've understood 😊
Thank you!!!
I've heard the term "API" tossed around for years by people who love to use jargon. Your video finally explained what they are and why they are so common. Thank you, and well done!
Thank you
Thank you. Next API Security | Hacking training video👨💻
Was looking for a video to watch while eating my supper. Why now eat and learn
Could speak about node.js and relation with Back-end and Database using API technologies
Thanks mate
thank you
Thanks!
Thank you Mike! Really glad you liked the video 😁
Really good
Thank you Sandip!
This is the best video explaining this concept. I am a designer and know some front end, and although I had a notion of these concepts, with this video everything is crystal clear.
Such explanations should replace those complicated ones of Coursera!
perfect!👌
CertBros, If you don't mind, Can you please share your mic model number and setup detail?
Beautiful
The simplest and the best explanation, thank You very much!
Thanks you so much for a simple to the point explanation. Best video that explains api, yet.
You are F**ing Good man...I always stay tuned to your channel awaiting your contents like a young man waiting for his favourite music to get played on his favourite FM station...I wish to meet you some day..you make my IT journey feel like biscuits.😂
Thank you so much Emmanuel 🙏 Really appreciate the kind words. Comments like these are why I keep making these videos. Good luck with your IT journey.
excellent
Exactly what I needed. Thank you !
Thank you Iulian! Good to hear it helped 👍
I like how the intro music is the hottest rap beat since 2007
now that's some thorough Explanation! thanks
